"Marathons", as Sol says, is "for anyone yet to reach their destination". It's a fitting description for the worldly, altruistic man, and, as he's done so many times before, he's managed to fit legitimate introspection within a smooth, ever-flowing hip-hop track. We're perhaps hearing a slightly more aggressive Sol here, too, but, given the track's subject matter and events in the world at large, we can't blame him. This one's another must-hear, as so many of his tracks are.
